SPECIFICATION forming part of LettersPatent No. 695,499, dated March 18,1902. Application led October 5, 1901. Serial No."7'7,709. (No model.)

To all whom it may oon/cern: l

Beit known that we,'JAMEs A. D. SHEE- FIELD and JOHN C. SHEFFIELD,citizens of the United States,residing in the county of Houston andAState'of Texas, have-invented a new and useful Oultivator-Plow, ofwhich the following is a specification; l

Our invention is an improved cul'tivator-I plow, especially adapted forcultivating cotton and other crops; and it consists inthe peculiarconstruction and combination of devices hereinafter fully set forth andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of acultivator-plow'constructed in accordance with our invention. Fig. 2 ispartly a side elevation and partly a sectional view of the same. Fig. 3is adetail perspective view of one of the adjustingplates used on thebeam for securing the standard brace-links at-any desired adjustment ofthe standards. Fig. 4 is a detail perspective View `of oneloftheclamping-links used forsecuring theshovels orpoints to the standards,Fig. 5 is a similar'view of one of the foot-blocks used in the sameconnection.

The beam Al is preferably made of wood and is provided at'its front endwith the usual clevis 2. The handles 3 have their front ends connectedto opposite sides of the beam by a bolt 4. A rung 5 connects therearportions of the handles together. A kwheel` is disposed under the rearportion of the beam and is mounted in a standard?, which iscomposed of apair of bars 7?, which bear against opposite sides of the beam, areconnected.

thereto by a bolt 8, which'passes through openings in said bars andbeams, and the upper ends ofthe said bars 7a are bent outwardly, as at9, and provided with adjustingopenings 10. Bolts 11, which are fitted inopenings with which the-handles 3 are provided, pass through appropriateopenings 10 and secure thesaid standards 7 at any desired angle withrelation to the beam, and this construction and combination of devicesalso enablesthe handles tobe adjusted vertically, so that their rearAends may be disposed at any desired height to suit Jthe plowman. Thebars 7 have adjusting-openings`12 in their lower portions to receive thebolt 13 or spindle on which the wheel 6 revolves, and hence `the lattermaybe adjusted vertically in the standard 7,`as willbe understood.

Our improved cultivator-plow is provided with a plurality of standards14 to carryshovels or points 15, which may be of any suitableconstruction and shape. The standards 'are disposed one in advance ofthe other and "in line with each otherand with the Wheel 6. Each of thesaid standards is composed of a pair of bars 14, which are connectedtogether' at their lower ends andthe upper endsof which are bentoutwardly in opposite directions, bear against opposite sides of thebeam 1, and are secured thereto by bolts 16, which pass through openingsin the upper portions of said standard-bars at points above and belowthe' beam, hence clamping the standards to said beam without weakeningthe latter by passing the bolt therethrough. B y loosening the nuts onthe said' clamping bolts the said standards may be adjusted to anydesired inclination, as will be understood. i

On the beam 1, at suitable distances in ad- Vance of the respectivestandards-14,"are secured adjusting-plates 17.- The saidad'justing-plates`have thei r` upper sides corrugated `thebealn by bolts 23,which lpass below the beam, and bolts 24, whichpass above the beam,andengage appropriate corrugations in the adjusting-plates 18. The saidbolts and the said adjusting -plates enable the said brace-links to beshiftedlongitudinally on the beam to dispose and secure the standards 14at any desired angle. l

Foot-blocks -25.are secured between the lower ends of the bars 14a ofeach standard 14 bybolts 26. The said foot-blockshave laterally-extending shoulders 27- at their lower front corners which -bear on the frontedges` of the standard-bars 14a.vv The shovels or points 15 are disposedon the front side of the said foot-block and atltheir upper lportionsbear against the front'sides of the standards Aroo H. Clamping-links 28,which are provided at their front ends with T- heads 29 and at theirrear ends with laterally-extending eyes 30,'are disposed between thebars 14a of standards 14, and their T-heads 29 are adapted to bear onthe upper sides of the said shovels or points. The bolts 31, which areemployed to clamp the shovels or points to their standards, pass betweenthe bars of the latter through the eyes 30 of the clamping-links, andtheir nuts or taps 32 bear against the rear sides of the said eyes 30.Hence the said bolts coperate with the said clamping-links to secure thepoints or shovels against vertical displacement on the standards andenable the said points or shovels to be adjusted vertically and clampedto the standards at any desired point.

By attaching appropriate points or shovels to the standards our improvedplow may be used for barring off between the rows of plants and sweepingearth up toward the plants when cultivating a cotton crop. Our improvedplow may be also used, when provided with appropriate points or shovels,for bedding and listing the soil or for banking or breaking out therows. It will be understood that by appropriately adjusting thestandards and the wheel 6 the points or shovels may be caused to run inthe soil to any desired depth. The wheel 6, which operates in thefurrows in rear of the points or shovels, materially lessens the laborto the plowman. At the end of a row, before turning, the handles shouldbe depressed to elevate the points or shovels,there by supporting theplow entirely upon the wheel 6,when the plow may be readily turnedwithout appreciable effort on the part of the plowman. The wheel 6,which operates in rear of the plow, also enables the plow to be readilymoved to any part of the field without permitting the points or shovelsto cnt the surface of the soil. By

having the points or shovels and the wheel in line with each other anddirectly in the line of draft under the beam the plow is enabled to runveryrsteadily and evenly without deviation from a straight line and isadapted to be readily guided.

Our improved plow is exceedingly cheap and simple, is very strong anddurable, and is entirely practical and efficient in operation.

Having thus described our invention, we claim l. In a plow, thecombination of a beam, handles pivotally connected at their lower frontends thereto, a standard comprising a pair of bars, disposed on oppositesides of the beam and pivot-ally connected thereto, the upper ends ofsaid bars being adjustably attached to said handles, and a wheel mountedbetween the lower portions of said bars, substantially as described.

2. In a cultivator-plow, the combination of a beam, a standard havingits upper end forked, to provide arms which bear against opposite sidesof the beam, clamping-bolts connecting said arms above and below thebeam, whereby the upper end of the standard is adjustable longitudinallyof the beam, an adjusting-plate on the latter, notched on its upperside, a brace-link connected to said standard, extending forwardly andupwardly therefrom and provided with arms which bear against oppositesides of said beam, and bolts connecting said arms and extendingtransversely above and below the beam, the upper of said bolts engagingsaid notched adjusting-plate, substantially as described.

In testimony that we claim the foregoing as our own we have hereto aixedour si gnaturcs in the presence of two witnesses.
